Yemeni forces kill three militants seen behind series of attacks

Yemeni forces on Wednesday killed three members of a militant cell who authorities believe attacked a German diplomat late last month and carried out assassinations in the capital Sanaa, a Yemeni official and a security source said.

The security source said a counter-terrorism unit raided a house in the Shmailah district in south Sanaa and killed three al Qaeda militants, Reuters reported.

"They were behind the attempted killing of the German diplomat," the security source said.
